4. Replacement Procedure for Absolute-Data Backup Battery
The replacement procedure will vary depending on if errors are present at the time of replacement and if
so, which errors are present (No.A23, 914, CA2).
If no error is present, perform steps (1) to (8).
If an absolute-data backup battery voltage-low warning (error No. A23) is present, perform steps (1) to
(15).
If an absolute-data backup battery voltage error (error No. 914 or CA2) is present, perform steps (1) to
(8), and then perform an absolute encoder reset by referring to Chapter 8, “How to Perform An
Absolute Encoder Reset.”
Note: Of the following steps, complete steps (3) to (6) within 15 minutes.
(1) Turn off the controller power (both the control power and drive power).
(2) Remove screws attaching the brake switch panel,
and take out the panel.
(3) Remove the applicable battery connector and pull out
the battery.
(4) Set the absolute-data backup battery enable/disable switch to the bottom position.
(Note) This operation is not required if no error has generated or when an A23 error has generated.
(5) Insert a new battery into the holder and plug in the
battery connector.
